One reason is that, when applying the sample by scraping it into the groove of the scraper blade, variations in force and speed occur among different operators. Another reason is that, during readings, judgments regarding particle count and distribution are subject to considerable subjectivity—particularly when rapid results must be obtained within 5 seconds or when using low‑range scraper blades (e.g., those with a range of 0–25 μm).

BGD 245 Intelligent Scraper Fineness Tester

Description

Product Introduction

The blade‑scratching method is the most traditional and widely used technique for assessing the fineness of pigment particles in coatings; however, obtaining results with high reproducibility and comparability can be challenging. One reason is that, when applying the sample by scraping it across the blade’s groove, variations in pressure and speed among operators are inevitable. Another factor is the considerable subjectivity involved in interpreting particle count and distribution during readings—particularly when rapid results must be obtained within 5 seconds or when using low‑range blades (e.g., those spanning 0–25 μm).

BGD 245 Intelligent Scraper Fineness Tester It is our company’s latest smart scraper fineness tester. This instrument not only automatically performs standardized scraping of the sample across the grooves of the fineness plate, but also instantly captures and saves images of the particles within those grooves. Furthermore, in accordance with the relevant standard’s numerical requirements, it can automatically determine the scraper fineness value of the test sample within 5 seconds. In addition, this instrument features the following characteristics:

◆ Automatically and rapidly measures the scraper fineness of samples, offering simplicity, convenience, high efficiency, and excellent reproducibility and comparability of test results.

◆ Compatible with various types of standard scraper fineness gauges: single‑slot (170 mm × 50 mm), double‑slot (175 mm × 65 mm), and wide‑slot (175 mm × 65 mm); the fineness plates are available in ranges of 0–25 µm, 0–50 µm, 0–100 µm, 0–150 µm, and 0–200 µm.

◆ Based on a deep-learning model framework, particle characteristics can be more clearly defined, enabling the identification and quantification of defects that interfere with judgment—such as pits, scratches, tiny bubbles, and bubble agglomerates—and their respective sizes.

◆ The display interface shows the current sample name, sample batch number, and test time. During operation, it indicates the step currently being executed by the instrument, the raw image after scraping, the algorithm‑processed image, the particle size distribution, and the final judgment results according to Methods A and B.

◆ To ensure that the readings are consistent with those obtained through traditional human visual inspection, the operator can freely set the threshold range for particle size detection. If a detected particle is smaller than the specified minimum threshold, it will not be included in the count; if it exceeds the maximum threshold and meets the criteria for a bubble, the system will classify it as a bubble. The operator can then choose, by checking a box, whether to treat such bubbles as normal particles in the final count.

◆ The original image and the particle distribution map can be freely magnified to examine specific regions, enabling operators to carefully compare and analyze the particles that the software has included or excluded.

◆ To accommodate samples with varying drying times, the operator can set the reading time after coating (0.5 s to 5 s), ensuring consistency across all tests.

◆ The user interface includes options for adjusting image-processing parameters (such as particle threshold settings), setting the analysis speed, defining the ROI detection area on the fineness plate, counting the number of particles, and providing a feature that allows users to manually select and remove interfering particles.

◆ High-precision motion control, combined with a high-accuracy imaging system, delivers crisp images and reliable results.

◆ Test results can be exported as PDF files.

◆ Compatible with both water-based and oil-based paints
